CHAPTER -7GALVANIZED IRON PIPES, SPECIALS AND GUNMETAL/BRASS METAL FITTINGS7.1 Applicable codesThe laying of GI pipes and fittings / specials shall comply with all currentlyapplicable statutes, regulations, standards and codes. In particular thefollowing standards, unless otherwise specified herein, shall be referred. In allcases, the latest revision of the standards/codes shall be referred to. Other IS:Codes not specifically mentioned here but pertaining to the use of GI pipes,fittings & specials shall be part of this Specification.I.S. NumberTable No. 7.1TitleIS: 1239 (PT-1): 2004 Mild steel tubes, tubular, and other wrought steel fittings,part 1 mild steel tubes.IS: 1239 (PT-II): 1992 -- Do part 2 mild steel tubular and other wrought steelpipe fittings.IS: 1978: 1982Line pipesIS: 4736: 1986Hot-dip zinc coatings on mild steel tubes.IS 778: 1984Copper alloy gates, globe and check valves for waterworks purposes.IS 2692: 1989Ferrules for water services.7.2 Gate valve as per IS: 778-19847.2.1 A valve through which the flow of fluid is controlled by means of a gate in theform of a wedge or disc between the body ends which are in line with eachother; the gate is actuated by a stem whose axis is at right angles to that of thebody ends. In the gate valves, the fluid pressure acts on one side of the gateand there is no change in the direction of flow.7.2.2 Globe valve (or Screw down stop valve)(See Drawing No.-6)A valve having generally a spherical body in which the body ends are in linewith each other and the disc is lifted from or lowered on to the body seat by astem whose axis is at right angles to that of the body ends. In globe valves, thepressure acts on the underside of the valve disc and there is a change ofdirection of flow inside the valve body.7.2.3 Angle valveA valve having generally a spherical body in which the body ends are at rightangles to each other and the disc is lifted from or lowered the body seat by astem whose axis is in line with that of one body end.Urban Administration & Development Department Page 74
7.2.4 Check valve (or Non-return valve)-A valve which permits fluid to flow in one direction but checks all return flow. Itis operated by pressure alone, having no external means of control. The flow iscontrolled by means of a disc raising and falling on to a seat with the fluidpressure (lift check); the flow may also be controlled by means of a flapswinging up and down with pressure on to a seat (swing check).7.2.5 End-to-End DimensionThe distance between the two planes per pendicular to the valve axis locatedat the extremities of the body end ports of straight type screwed end valves.7.2.6 Face-to-end DimensionThe distance between the two planes per pendicular to the valve axis locatedat the extremities of the body end ports of straight type flanged valves.7.2.7 Centre-to-End DimensionThe distance between the two planes located at the extremity of either bodyend port and perpendicular to its axis in the case of angle type screwed endsvalves.7.2.8 Centre-to-Face dimensions-The distance between the two planes located at the extremity of either bodyend port and perpendicular to its axis in the case of angle type flanged valves.7.3 Classification of valves: The valves shall be of two classes as under:-7.3.1 Class 1 valves- Valves of this class are suitable for non-shock cold workingpressure up to 1.0 MPa (cold service means a temperature not exceeding45c7.3.1.1 Class 2 valves- Valves of this class are suitable for non-shock cold workingpressure up to 1.6 MPa.7.4 Types of valves:-Valves shall have screwed or flange ends, integral or renewable body seatsand screwed-in-, screwed-on or bolted bonnets or covers.7.4.1 Gate valves- The gate valves shall be of the following types, having insidescrew with rising or non-rising stem or outside screw with rising stem.a) Solid Wedge Type (in which the gate shall be one-piece and solid exceptfor the ole not more than 2 mm in the diameter for the spindle for the size of upto and including 25 mm, and not more than 3 mm for sizes above 25 mm toaccommodate the spindles; and in which no material has been removed fromthe surface of the gate.):b) Split wedge type; andc) Double disc typeUrban Administration & Development Department Page 75
